Garmin has announced its latest GPS navigation product, the StreetPilot 2820. The 2820 features Bluetooth and hands-free calling interface. The wireless Bluetooth feature allows calling from a contact list or the stored phone number directory of locations such as hotels, restaurants and stores, and of course there is hands-free navigation with voice commands. Along with the hands-free and navigation options the 2820 can also be a block-rockin' MP3 player. Should be available in June for $1,099.
